I've set the apache confs to use the following

I reran the test with a smaller load (350 users as opposed to 1250). It didn't hit the server limit but I still get this error:

That means that when ajp_ilink_receive() (actually ilink_read())
tried to read from the AJP socket, it rec'd an error.
Could be a network issue. Could be not enough workers on
the Tomcat side.
